Reliable Intrinsic Safety for Hazardous Areas

The MTL 787+ Shunt-Diode Safety Barrier is purpose-built for hazardous area process control, providing energy-limiting protection for field and control room equipment. Its single-channel design supports DC signals and protects circuits by employing the shunt-diode principle. Maintenance-free and robust, it offers an optimal, passive approach for safe automation environments, ensuring operational integrity without the need for external power.


Compact and Durable Construction

Crafted with a flame-retardant thermoplastic housing and reinforced by aluminium encapsulation and stainless steel screws, the MTL 787+ combines lightweight design (approx. 70g) with durability. Its space-saving dimensions and DIN rail compatibility make installation in control cabinets swift and convenient, while IP20 protection and reliable material selection ensure longevity in industrial settings.

FAQ's of MTL 787+ SHUNT-DIODE SAFETY BARRIER:


Q: How is the MTL 787+ Shunt-Diode Safety Barrier typically installed?

A: Installation is straightforward, as the barrier is designed for DIN rail mounting. Connections are made using screw terminals and test jacks, supporting both field and safe area wiring with simplicity and reliability.

Q: What is the primary benefit of using a shunt-diode safety barrier in hazardous areas?

A: The main advantage is intrinsic safety. The shunt-diode principle restricts the energy in field circuits, greatly reducing the risk of ignition in explosive atmospheres. This protection is crucial for process control applications where safety is paramount.

Q: When should I select the MTL 787+ for my process control system?

A: Choose this barrier when you need to ensure intrinsic safety for DC instrumentation in hazardous locations, especially where passive, maintenance-free protection and compatibility with various field devices are required.

Q: Where is the MTL 787+ most effectively applied?

A: This device is best used in sectors such as oil and gas, chemicals, and pharmaceuticals-anywhere process control instrumentation in hazardous zones needs secure, flameproof encapsulation and intrinsic safety compliance.

Q: What is involved in the maintenance process for the MTL 787+?

A: No routine maintenance is required because the barrier is a passive device with no moving parts or power requirements. Its robust construction ensures long-term operational reliability.

Q: How does the device ensure secure connections and easy testing?

A: The MTL 787+ barrier provides dedicated test jacks for both field and safe area wiring, allowing for quick field device testing and verification during installation or troubleshooting.

Q: What are the usage limitations regarding current, voltage, and temperature?

A: The device supports a maximum current of 300mA, operates up to 28V DC, and is suitable for environments ranging from -20C to +60C. Load and cable length should be chosen according to installation parameters to maintain compliance and performance.
